Application filed March 6, 1917. Serial No. 152,732.

To all whom it may concern:

Be it known that 1, JOHN C. SGHRADE, a citizen of the United States, andresident of Rockaway Beach, in the county of Queens and State of NewYork, have invented certain new and useful Improvements in Pipe- Seals,of which the following is a specification.

The present invention relates to the class of water distribution and hasa particular reference to new and useful improvements in seals forvitrified and cement pipe sewers.

The primary object of my invention is to.

provide a closure means forthe' mouth or bell of the vitrified or cementpipe which may be constructed at a small cost, that is adapted to bedetached without injury to the pipe, and yet having the desiredcharacteristics to provide a permanent pipe seal if such be desired.

A still further object of my invention is to provide a pipe closure ofthe class described which is adapted to be used with Y or T branchesas-we'll as with the main pipe line.

Other improvements and novel details in the construction and arrangementof the various parts of the apparatus will be brough out more in detailin the description to follow, which, for a clear understanding 4 thedeslred airtlght and waterproof closure.

of the invention, should be considered in connection with theaccompanying drawing, forming a part hereof, and wherein is disclosed,for the purpose of illustration, convenient and satisfactory embodimentsof the invention. It is to be noted, in this connection,-that minorchanges in the construction and details of the invention ma be madewithout departing from the spirlt or scope of the invention.

In the drawing:

Figure 1 is aperspective view of my invention, and

Fig. 2 is a longitudinal sectional view thereof.

Corresponding and like parts are'referred to in the followingdescription and indicated in all of the views of the drawing by the samereference characters.

My improved pipe seal or closure com-' prises a cap member, designated Cin its entirety, having an end portion 11 provided with a concentricallyarranged inwardly extending enlargement 12 adapted to be seated at thejointure of the end of the pipe 13 with the mouth or bell portion 14thereof. A laterally extending flange 15 is provided on the edge of theend portion of the cap member and is adapted to embrace the bell orflared mouth portion and also a part of the pipe. The flange 15 isprovided with grooves 16 for a purpose which will be hereinafterdescribed. Semi-circular indentures 17 are provided on the oppositesides of the cap member to permit that portion thereof within thesemi-circular indenture to be removed and thus permit the use of myimproved cap with a Y or T branch.

To provide means for facilitating the breaking or removal of the end.portion 11, an annular groove 20 is formed therein. Thus by tapping thesame with a hammer or other suitable implement, the end may be readilybroken from the cap. I

After thecap member has been inserted over the head of the pipe to beinclosed and the enlargement 12 is resting on the end of the pipeadjacent the jointure of the bell or I mouthpiece thereof a piece ofoakum or'jute 18 is. inserted between the bell portion 14 and the sideof the cap after which concrete 19 is inserted between the exposed endof the cap and the ipe. After the concrete settles and becomes ardenedthe same will provide When it is desired to remove the cap portion afterthe same has accomplished the desired purpose, by a strike of the hammerthe cap member will break along the groove portion 16 and thus permitthe removal thereof. It

is of course to be understood that my cap member is made of concrete orearthenware, having the grooves and indentures abovementioned markedtherein before the same has become burned, z. 0., before it has beenplaced in the roasting furnace.

Havin thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. In a device of the class described, the combination with a pipe and abell portion provided on one end thereof, of a cap member adapted toembrace the said bell portion and a portion of the pipe and having aplurality of longitudinally extending grooves therein.

2. In a pipe seal, a cap member having a plurality of semi-circularindentures therein providing-means for facilitating the removal of thesemi-circular portion Within the'semicircular indentures to adapt thecap member for use With various designed pipes.

3. In a pipe seal, a cap member having a plurality of longitudinal andsemi-circular grooves formed in the sides thereof and an annular grooveformed in the end thereof, said longitudinal groove terminating atpoints adjacent the annular groove, as and 10 for the purpose set forth.

In testimony whereof, I aflix my signature hereto.

JOHN C. SCHRADE.
